11" coil issue

[Puffin]

I picked up an 11" coil a few weeks ago. Managed to use it for the first time last week on a freshly cut wheat stubble field. started off fine in Deus Fast. Part way through the day it became over sensitive to being in contact with the stiff stubble. Particularly in the 9 and 3 o'clock portions of the coil. 12 and 6 o'clock are fine and no reaction to contact. As it was the first dig of my Detecting clubs new season I carried on and found a very nice one of these, click on Lima for the history 1745 silver Lima shilling of George II

However, even after cleaning and removing the coil cover just in case I'd got a metal fragment in there, I'm still getting chatter and a reading of 97 when the coil comes into contact with anything anything, as you do when detecting in stubble. Tried reducing the sensitivity down to 80 and its not as bad. Just wondering if I've a duff coil?

Any ideas guys?

I am very new to this and I'm not sure if it is a coil defect, but perhaps the Ground Notch function can help you out in the meantime?

This guy shows you how to do it at some point during the video. https://www.youtube.com/watch?v=kjuANf3J3yg He mentions the falsing when it gets knocked around.

I've used Ground Notch (85-90) when getting the bump faulting/chatter and it work very well for me.
Also helped eliminate the chatter when I set it down to dig.

Ground balance off can cause hyper sensitive coil in some cases....

 

[ecoast]

can you swap coils w/ a buddy and see result?

I think Ray hit it right on the head. It sounds like a ground balance issue. For some reason running the Deus in the 90 position is the best thing you can do. Try that. I notice today that when I had the Deus shaking the coil while the Deus was in tracking made it sound off. I switched to 90 manual and it went away. As a side note I will tell you the tracking was at 78.

Your erratic behavior is normal when running in ground track at ground readings above 80.
Either use ground notch or go manual GB.

Thanks guys, I'll have a look at this, this weekend hopefully.

OK guys, after playing with various settings on a very wet and muddy field this last Sunday. I gave up and took the coil back to the Main Dealer here in the UK. Nigel at Regtons, Sorted it in minutes, Seems XP are constantly tinkering with the software. Software 3.2 has had a good number of minor issues fixed since its release. All he did was update the software.

He went on to suggest that a regular update programme should be the norm, because XP are still doing minor tweaks to the V3.2 programme.

LOL so 3.2 should be named 3.3 or 3.2b you would think....

Thanks for passing on the info!
